FreeBSD has a reputation of being slow in combination with MySQL, especially when compared to Linux. However, some recent improvements in the scheduler shows that FreeBSD now is pretty much on par with Linux. It also shows that Linux scales very badly after a certain amount of threads per CPU.

To be fair, Linux has stolen the OSS spotlight and so I think any news that a *BSD is still competitive (and in some areas even better) is fair play. I'm a Linux user, but I respect and appreciate the work the *BSD community has done, much of which is used in Linux.
